Very new to the platform and making music for commercial use - Advise needed

Hi everyone,

literally just want some pointers on how to use the platform, does and don'ts.

- can I see if people are listening to my music anywhere or only if they buy it?
- Any pricing guides?
- any advise around tagging?
- I've received a $1.58 subscription payment, but I can't find anywhere what its actually for, did someone buy one of my tracks?

Cheers!
